Example Embodiment

[0041] The present invention will be further described below in conjunction with specific embodiments.

[0042] There is a lot of information in life, such as voice, text, face, fingerprint, etc., which cannot be directly recognized by computer. Now, with the development of artificial intelligence deep learning technology, these information can be processed into vectors that can be recognized and recognized by computers. The computer compares the similarity of two vectors by calculating the Euclidean distance, cosine distance and inner product of the vectors. . And vector retrieval is the technique of storing and looking up these feature vectors.

[0043] The embodiment of the present invention provides a vector retrieval service data management method based on a domestic CPU and OS. The implementation of the method includes index file type selection, vector insertion, data file management and vector query, wherein,

[0044] In the vector insertion stage, data is added to the m

Abstract

The invention discloses a vector retrieval service data management method and system based on a domestic CPU and an OS, and belongs to the technical field of artificial intelligence and vector retrieval, the implementation of the method comprises index file type selection, vector insertion, data file management and vector query, meanwhile, the data are added into the log file, and the memory index is readable and can be directly searched during query; when the data volume in the memory index reaches a specified volume, storing the data in a disk, deleting a data log file corresponding to the part of data, and establishing a new index in the memory for adding the next inserted data; creating two tables to manage information of the file; and when a query request is received, querying the data which is just inserted but is not stored in the disk, and querying the data which is stored in the disk. According to the method, the problem of data management of domestic CPUs and OSs based on Fiss vector retrieval service can be solved.
